The isomeric (+) and (−)-dihydromyrcene cyclise in organic acids through a stereospecific ring contraction process to give the esters of α-(S)-(+)-1-(α-hydroxyethyl)-3,3-dimethylcyclohexane and α(R)-(−)-1-(α-hydroxyethyl)-3,3-dimethylcyclohexane respectively. Small amounts of enantiomeric cis- and trans-tetrahydroeucarvyl esters are also formed. The absolute configuration of the chiral carbinol centres
